Fred Rogers rehearses the opening of his PBS show "Mister Rogers' Neighborhood" during a taping in this June 28, 1989, file photo in Pittsburgh. A tribute to children's public television pioneer Fred Rogers will include an effort to get people everywhere to wear a sweater on what would have been his 80th birthday. Family Communications Inc. of Pittsburgh is promoting March 20, 2008, as "Sweater Day" to honor Rogers, who died of cancer five years ago. A sweater was his trademark garb on "Mister Rogers' Neighborhood." (AP Photo/Gene J. Puskar)
